Considering purchase of new Okuma LB3000 - Need advise, big bore or standard bore?

InventIt · Dec 11, 2019

Hey Boys,

I been thinking about taking advantage of Okuma Year End Promos on in stock 2019 machines. Looking at the LB3000MYW Lathe to replace the 2 axis LB15 I currently have. Dealer has either a standard bore with 450mm bed or a big bore with 800mm bed. Most(95%) of the parts I make would be smaller diameter, shorter length (think .25Dia up to about 2" Dia.) and well within the range of a 450mm bed. So the 450Bed with the standard bore would be fine for those parts. Thing is, this would be my only cnc lathe in the shop and I really think it would be nice to have the longer bed for those rare jobs that come up occasionally. There have been a few times I have pushed the Z limits on the LB15 and had to get creative

. Question is if I went with the big bore in order to get the longer bed length would it be such a bad fit for the smaller work that I would end up disappointed with my choice? The standard bore gives 2.5" thru spindle with 5000rpm. The BB gives 3" thru spindle with 4200rpm. Oh, one more thing, none of this is high production work. So, I'm not sweatin a few seconds more cycle time per part if the big bore is gonna be a little slower.

Thanks for the input...

Big bore sure does come in handy when you need it....

Hello.
I have the big bore. Its great as I was able to feed 3 inch bar through it which came in handy a few times. Also I think the BB is a little bit bigger than 3 inches. Consider getting one of those quick collet chucks.

We have the 450 bed with the sub spindle, i would highly recommend the long bed. Regardless of part size , the machine is really tight with the sub spindle. It's a pain to set up tools as is . I got to look through the long bed version last month and was quite jealous. The overall machine size is similar since they hang the control on an arm instead and put a second door that opens towards the sub.

Big bore is worth it.
As for length... no matter how long your center-to-center is you'll always need a longer one lol.

Get the big bore longer bed.
It's like sex and computer memory, you can never get enough.

The only reason I could see for getting the shorter machine is to fit it into a tight spot in your shop. If you have the room, get the bigger machine (good choice by the way -- just got our 3rd LB3000 -- love them).

Yeah, I can see how the long bed would be nice to have. I was mostly concerned about running small parts in a big bore machine.

I have never bought a new machine before. What are your experiences with dealers as far as bargaining on price or getting extras thrown in? Talking to the dealer, I got the feeling the price was "take it or leave it" haha. Should I try to get them to sweeten the deal a little?

Hello we paid 160k for ours all in. As we were looking at a takisawa the dealer matched what the opposing dealer was offering as well as all the holders that came with the takisawa. If they smell money in your account they will and should fight. Hope this helps.

Wow! 160k? That seems like a really good price. They quoted 178k for the showroom machine, BB 800bed, 8"&6" chucks, think it may include a set of static holders. Nothing more. What was included on your machine? What options did you get? Thanks

My long bed with milling (LB 3000 M x 1000 bed) was about $155,000. Throw in y-axis and subspindle, and 178k might be a pretty good deal. I think I got about 5 live tools plus regular turret tooling. Definitely tell them you are interested in a few other brands and try to get the best deal you can.

That sounds like a really good deal. Was it a demo?

I dont think so. it was in 2014-2015

The end of the Obama years. Prices were probably lower when we were all being told that manufacturing jobs were going overseas forever.

I am terrible at haggling. I think we got the chuck because they were running a special. 5 collets free chuck thing or vise versa.

Panza · Dec 16, 2019

Get the long bed: It gets's terribly tight in sub-spindle machines. And if you have boring bars or axial live tools on both sides of a holder and then parts in both spindles... :crazy:

InventIt · Dec 16, 2019

Hey Guys, Thanks for your input. And, thanks for posting the pricing info. Plutoniumsalmon makes me think I'm gettin raked over the coals :rolleyes5:

Wow! that is a great deal you got!

I have an appointment tomorrow to look at the one they have in their show room. That's the long bed BB. They want 178k for it. has like 14 hrs on it.

camhead420 · Dec 17, 2019

i have run both big bore and standard, i only thing about the big bore is clamping on smaller than 7/8" parts. It takes more time to make soft jaws to hold the small parts. We have one Okuma with a 12" chuck (all others are 10"), didnt know we were getting it,no one ask us, guess what boss? i need all new jaws, whoops!

tts197 · Dec 18, 2019

I cant find the paperwork now but I'd bet money there was 3 options. We had bought one just last year before I left the job shop i was at.

there was the standard. a big bore varient, and a super big bore with a special draw tube and maybe an additional support inside the draw tube for large material. I will look more.

FWIW 278K
1500mm bed
12" standard chuck
y axis
tooling package
full igf
tool comp
program tail stock
standard chip convey

It was probably bigger than we needed but to go from the 30" bed to the 60" was something stupid like 7500 bucks so we went with it.
